A 12-point inspection checklist used by our engineers before every walk-through. Covers system age indicators, preservation red flags, energy waste signals, and the questions your contractor should be answering before you sign anything.
"Vestry was the first contractor who walked in and looked up — not at the equipment room, but at the ceiling. They understood immediately what we were dealing with."
44% energy reduction"We'd been told three times that geothermal wasn't possible in a building this old. Vestry said 'we've done it before' and then showed us the project file."
11-year payback achieved"The SHPO approval process alone would have stopped any other contractor. Vestry handled it as part of the project scope. Zero additional cost."
